Binary format:
	is_conditional[1], instruction id[remaining bits]


is_conditional:
	n: number of bits in first parameter
	s: minimum number of bits required to represent (number of bits for current mode - 1)
	/: integer division

	Appends 2 parameters to the normal parameter list for the instruction:
		First parameter:
			Lowest (n-s)/2 bits:
				Which bits to check
			Next (n-s)/2 bits:
				Value for each of the above that it should match
			Remaining bits:
				Bitwise offset into second parameter for value to be used
		Second parameter:
			Value to be used

	Conditional instructions will be executed after unconditional ones

	Conditional instructions will never set flags, if a conditional instruction references another, it will always be based on null flags

Exceptions:
	If (s+2) > n:
		Triggers `illegal instruction` exception
